Ultra Rock Flower Anemone

If your reef tank needs a little wow factor, Ultra Rock Flower Anemones are about to steal the spotlight. These vibrant stunners are the fluorescing variety of the classic rock flower anemone—meaning they practically glow under the right lighting. From electric greens and neon oranges to cosmic purples and rainbow blends, each one brings something different to the table (or sandbed).

Rock Flower Anemone Breakdown

Native to the Caribbean and part of the Phymathidae family, rock flower anemones are known for their beaded tentacles and colorful oral discs. They bury their bodies and chill in place, making them a low-maintenance addition that still turns heads. At Foxy Saltwater Tropicals, we source our Ultras directly from the waters off the Florida Keys—hand-selected for the boldest, most unique colorations we can find.

Spotlight on Our Ultra Rock Flowers

  • Fluorescing Colors: These anemones pop under blue spectrum or LED lighting—perfect for that nighttime reef glow-up.
  • Semi-Stationary Stunners: While they’re generally known for staying put, Ultra Rock Flowers might decide to shift around until they find the perfect spot. Keep an eye on them early on—they usually settle down once they’re comfortable.
  • Perfect for Packs: Pick a single showstopper or grab a variety pack to start your own technicolor garden.

Caring for Ultra Rock Flower Anemones

  • Lighting & Flow: Blue LEDs are your best friend. Medium flow keeps them happy and their tentacles swaying.
  • Feeding: They’re meat-eaters. Toss in chopped fish, mussels, or frozen reef food a few times a week.
  • Size Potential: Up to 8 inches across—so give them a little room to spread out.
